So in the early 80's the original story of Return of the Jedi changed quite a bit. Per Gary Kurtz, the early versions of Return of the Jedi the story elements were: Han Solo is rescued from Jabba the Hutt Han Solo DIES in Act 2 during a raid on an imperial base (Endor? Kashyyyk?) Leia was not Luke's sister The allies in the final land battle were wookies not ewoks. There was no Death Star 2 There was little or no Palpatine (they were saving him for Episode 9 originally) Luke defeats Vader but goes to the dark side in the process and leaves on his own without the rebels. Leia becomes queen and is in charge of the tattered rebel forces leaving room for a sequel trilogy (the current ending ROTJ kind of wraps things up in a nice bow). If there are more details to the original story please let me know.
